Presentation

minimal degreeμ(G) = 28
transitive degreeμt(G) = 128

A minimal faithful permutation representation — 5 generators on 28 points:

(2,4)(5,6)(7,11)(8,9)(10,12)(16,24)(19,26)(22,28)(25,27);(6,9)(10,11)(13,14,17,20)(15,18,23,21)(16,19,24,26)(22,25,28,27);(1,2,3,4)(5,6)(7,10)(8,9)(11,12)(13,14)(15,21)(16,19)(17,20)(18,23)(22,27)(24,26)(25,28);(5,7,8,12)(6,10,9,11)(13,15)(14,18)(16,22)(17,23)(19,25)(20,21)(24,28)(26,27);(13,16)(14,19)(15,22)(17,24)(18,25)(20,26)(21,27)(23,28)
